You are printing on paper that curls easily.
Printed colors may appear uneven on the leading
edge of paper that is susceptible to curling. Increase
the level of vacuum holding the paper against the
Platen or specify a margin of 20 mm (0.79 in) or more
for the leading edge.

Auto Cut
in the printer driver before
printing. In this case, the paper can be printed without
borders on the left and right sides only. Cut the
printed document ejected from the printer, then use
scissors to cut away the edges on the top and bottom.
When using Borderless Printing, the edge of the
paper is cut during printing. Thus, ink density may
not be even at the edges.
